WAGO I/O System 750
750-940 EnOcean RS-485 Gateway; 868 MHz
Manual
Version 1.3.0, valid from FW/HW Version 01/01
3.2.1.2 Connection for Single Lines
The signal line connection is made through a 5-pole, 2-wire modular PCB
connector that accepts the individual wires and is plugged into the 5-pole PCB
male header X2 of the EnOcean Gateway; see Figure “Connections on the
EnOcean Gateway.”
Only connect common connection with galvanically isolated devices.
The common connection (“com”) must only be connected with galvanically
isolated devices.
Otherwise, current loops may occur.

Connection for External Antenna
The external antenna is connected via an SMA socket. The shielding is
connected directly to GND.
Only use the Magnetic-Mount Antennas from WAGO.
Only use the WAGO Magnetic-Mount Antenna GSM 850/2100 (Art. No.:
758-911) as external antenna for the EnOcean Gateway.
The technical properties and compliance with the EMC and R&TTE Directives
are only ensured when these antennas are used.
